STICKER-ROD FISHING TUOI'.

`Application led May 13, 1925. Serial No. 39,004.

v vented certain new and useful Improvements in Sucker-Rod Fishing Tools, of which the following is a specification.

The present invention appertains to a fishing tool especially designed for engaging and pulling out broken sucker rods form a well.

The prime object of the invention is to provide a sucker rod fishing tool of this nature, which is efficient and reliable in operation, easy to manipulate, strong, durable, .not likely to become easily out of order, inexpensive to manufacture, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view, as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combina-tion and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is an elevation of the tool embodying the features of our invention.

Figure 2 is a longitudinal section therethrough.

Figure 3 is a bottom end elevation of the tool and Figure 4 is an enlarged detail view of the movable slip.

Referring to the drawing in detail, it will be seen that A designates generally the casing, in which is slidably mounted a movable slip B and a stationary slip C. The casing A has its lower end 5 of a cylindrical formation, with the inwardlyv bevelled edge (i. The upper portion of the casing A has its side open as at 7 and is provided with a longitudinally extending slot 8. A stop 9 is provided above the upper end of the slot 8. A suitable coupling device 1() is fixed to the upper end of the casing A.

The fixed coupling C is arcuate in cross section and has its edges tapered as is indicated at 11. The edges adjacent the upper `end of the fixed slip C are provided with shoulders 12 which have. a dove tailed Jormation. The lower edge of the fixed slip C is bevelled inwardly as at 13. The upper edge thereof terminates a slight distance below the upper edge 14 of the cylindrical portion 5 of the casing A.

The movable slip B includes a body 15 which is arcuated in cross section, terminating at its lower end in an enlarged head por tion 16, also arcuate in cross section, but larger than the body, thereby forming a shoulder 1.7. A screw, rivet or the like 18 is fixed to the body 15 and rides in the slot 8, thereby slidably mounting the movable slip in the casing. A tongue extension 19 depends from the lower edge of the head 16 and has its median dimension aligned iwth the median dimensions of the body 15 aid the head 16. The lower edges of the head 1G form dove tailed shoulders 20 for cooperation with dove tailed shoulders 12. rIhe lower end of the tongue extension is bevelled as indicated at 21.

This fishing tool is let down into the well, in theusual manner and the upper end of the broken sucker rod engages the bevelled edges 6 and 13 and moves upwardly through the cylindrical portion 5, at the same time moving the movable slip B upwardly, until the coupling portion 22 of the sucker rod Q23 engages in the opening T, at which time the. movable slip will drop down so that its shoulders 20 rest on the shoulders 12 of the fixed slip C and then by pulling the casing A upwardly, the coupling portion Q2 will rest on the upper edge of the fixed slip C and the Shoulder 17 of the movable slip B and the rod or rods may be pulled from thc casing.

It is thought that the construction, operation, and advantages of the invention should now be clearly understood by those skilled in this art, without a more detailed description thereof. It is desired, however, to point out. that numerous changes in the details of construction, and in. the combination and arrangement of parts may be resorted to, without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described our invention, what we claim as new is:

A sucker rod fishing tool of the class described including a casing, a fixed slip, and a 'movable slip, said casing including an upper portion arcuate in cross section, and a lower portion circular .in cross section, said upper portion having a longitudinally extending slot disposed on the median dimension thereof, said fixed slip being fixed in lill llO

the Cylindrical portion opposite to the slot, said fixed slip being arcuate in cross section and having its upper portion of tlie longitudinal edge out away to forni dove tailed shoulders, said movable slip being` arcuate in Cross section and provided with an elongated body having an enlarged head formed on itslower end thicker than thebody to provide an interior shoulder, the lovvei` edge of 0 the head being dove tailed to forni shoulders for cooperating with the shoulders on the fixed slip, an element projecting' from the vbody of the movable slip into the slot for moyably mounting the movable slip in the casing.

In testimony whereof We afix our signatures.
